Jenna Jameson has written an erotic novel.

The ex-porn star's first foray into fiction, 'Sugar', will be published in October and the story revolves around a former X-rated actress who moves to New York City to start a new life away from the adult industry.

Jenna admits writing the book was a challenge but she is confident her racy past career and appreciation of romance will give women an exciting read.

She told '''SUGAR' is something new and exciting for me. I've never written anything like this before and it was a wild ride. I've always been romantic and probably a little kinky. The time was right for me to express myself in 'SUGAR'. I think it's the hottest thing you'll ever read.''

Jenna - who has starred in such films as 'Hard Evidence', 'Jenna's Tough Love' and 'Camera Sutra' - is no stranger to the publishing world.

Her 2004 autobiography 'How to Make Love Like a Porn Star' sold over 250,000 copies and spent six weeks on the New York Times Best Seller list.

Jenna - who raises four-year-old twin boys, Jesse and Journey, with former UFC champion Tito Ortiz - insists her memoir was a very different book because it was a ''personal journey''.

She said: ''My memoir was a very personal journey for me, but a lot has changed in my life since it was published.''

There has been a boom in erotic publishing since the success of the 'Fifty Shades of Grey' book series by E. L. James which have sold over 70 million copies worldwide.
